Is there Unruh radiation?

0 Is there emitted radiation in Unruh effect ?

The thermal radiance felt by a uniformly accelerated detector/oscillator/atom– the Unruh effect [1] – is often mistaken to be some emitted radiation detectable by an observer/probe/sensor. Here we show by an explicit calculation of the energy momentum tensor of a quantum scalar field that, at least in 1+1 dimension, while a polarization cloud is found to exist around the particle trajectory, th...

Unruh Radiation with Ultra - Intense Lasers ?

ABSTRACT We point out that using the state-of-the-art (or soon-to-be) intense ultrafast laser technology, violent acceleration that may be suitable for testing general relativistic e ects can be realized through the interaction of a high intensity laser with a plasma. In particular, we demonstrate that the Unruh radiation is detectable, in principle, beyond the conventional radiation (most nota...

Hawking-Unruh Radiation and Radiation of a Uniformly Accelerated Charge

Hawking-Unruh radiation is a measure of the quantum fluctuations in the radiation of accelerated charges. In the case of uniform acceleration, the existence of Unruh radiation adds confidence that radiation exists at all, and helps clarify aspects of the equivalence between radiation in uniform acceleration and in a uniform gravitational field. 1 Hawking-Unruh Radiation According to Hawking [1]...

Radiation exposure during percutaneous nephrolithotomy; Is there a risk of the patient and the operating team?

Background: The aim of this study was to calculate the radiation amount exposed during percutaneous nephrolithototomy (PCNL) and to make the urologists and other staff sensitive about the radiation risk they were exposed to. Materials and Methods: We measured the radiation exposure during 114 cases of PCNL performed. Thermoluminescent dosimeters (TLD) were placed between the operation table and...
